Answer:
46x-22
Step-by-step explanation:
5(12x-3)-7(2x+1)
60x-15-14x-7
60x-14x-15-7
46x-15-7
46x-22
C. 2g-19.5=40 I think i'm right
2x+30y=12x+17
30y=10x+17
y=(10/30)x+(17/30)
x-intercept:
0=(10/30)x+(17/30)
-17/30=(10/30)x
-17/10=x
Given that

attains a maximum at

, it follows that

at that same point. So integrating once gives



and so the first derivative is

.
Integrating again, you get


You know that this curve passes through the point (2, -1), which means when

, you have

:


and so
